pass internal table into body of mail in task sendmail

Hi everyone, i use task sendmail, I want pass the contents of internal table MB_ITAB into body of message. In the property of task Mail, I wrote &MB_ITAB& but in output I have only the first line of internal table; naturally if write

&mb_itab[1]&,

&mb_itab[2]&,

&mb_itab[3]&,

&mb_itab[4]&,

&mb_itab[5]&,

&mb_itab[6]&,

in output I have the contents of internal table.

How can bind the complete contents ?

Thanks a lot,
